Apple PowerBook 520 and 540 Series model batteries are over 3 years old and Ni-Mh Cells have a maximum 3 year shelf life. This means you are not getting 100% battery capacity even if it is new and sealed in the box.
All you have to do is mail us your old battery (We will email you a pre-paid postage label with delivery confirmation - US customers only). After we receive it, we will send you a 100% tested Genuine Apple Refilled 4000mAh Battery to ensure that it will equal or exceed your original battery's life. Every battery comes with a 1 Year Warranty!
NOTE: If your battery is completely dead, you may still send it to our facility for a refill service. If we are unable to refill the battery, we will send you back your battery pack and credit you a full refund, including shipping. (Applicable to this battery model only.)
So, with nothing to lose, why not try our refill program today!!
To order a new battery without a Refill:
If you would rather just purchase another battery with longer running cells, purchase one at our low price and you will be shipped a fresh, new super-capacity battery.

The battery capacity increases every few months and the Apple PowerBook 520 and 540 Series battery packs have a 2200 mAh capacity Sanyo Ni-Mh cells. The new cells we are using to replace your batteries are 4000mAh LG Chemistry Cells. As a result of the refill service, a 2200mAh capacity Ni-Mh battery pack increases to 4000 mAh capacity.
This means longer run-time (80% higher capacity) compared to the original without causing any incompatibilities.
